Abstract
Abstract An apparatus is provided for mounting O-rings on male members such as pipe fittings, the apparatus comprising a substantially cylindrical mandrel of a diameter adapted to receive a supply of O-rings, and being flared at one end and having an axial chamber provided in said flared end adapted to receive the end of the male members. The mandrel is suitably mounted on a frame and is provided with a finger assembly which upon actuation receives an individual O-ring and moves it axially over the flared portion and causes it to be released therefrom and mounted onto the male member at a position provided therefor. In an improved embodiment means is provided for automatically feeding O-rings over the small end of the mandrel while the apparatus is in operation. In its broad sense the invention includes an apparatus for mounting an elastic annular member on a hub or wheel which is in part of greater diameter than that of the opening of the annular member, as for example mounting a buggy or automobile tire on the rim portion of a wheel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
282 words
An apparatus for mounting O-rings over the male end of a part fitting at the desired mounting position, which comprises a. a supporting frame, b. a mandrel detachably mounted on such frame having crosssectional dimensions sufficiently small to permit O-rings to be mounted to slide readily down the sides thereof over a substantial portion of its length, one end of said mandrel being flared to cross-sectional dimensions greater than that of the normal diameter of the openings of said O-rings, c. an axial chamber provided at said flared end having crosssectional dimensions sufficient to receive the end of the fitting upon which the O-ring is to be mounted, and of sufficient length so that when the end of said fitting is completely inserted in said chamber, an O-ring which slips off the edge of said flared end is received directly over the desired mounting position on said fitting; and d. means for engaging a single O-ring and moving it axially over said flared end, thereby mounting said O-ring over a fitting contained within said axial chamber, comprising: 1. a support, 2. a pair of fingers pivotally mounted on said support and spring biased toward the closed position, 3. means defining a pair of converging cam surfaces, and 4. cam follower means provided at an end of each of said fingers, the arrangement being such that in approaching the uppermost position said cam follower means engage said cam surface means and cause said fingers to open, thereby permitting an O-ring to fall past said fingers, and e. means positioned above said pair of fingers adapted to support a plurality of O-rings mounted on said mandrel and to release a single O-ring on actuation.
Claim 2
Independent Claim
282 words
An apparatus for mounting O-rings over the male end of a part fitting at the desired mounting position, which comprises a. a supporting frame, b. a mandrel detachably mounted on such frame having crosssectional dimensions sufficiently small to permit O-rings to be mounted to slide readily down the sides thereof over a substantial portion of its length, one end of said mandrel being flared to cross-sectional dimensions greater than that of the normal diameter of the openings of said O-rings, c. an axial chamber provided at said flared end having crosssectional dimensions sufficient to receive the end of the fitting upon which the O-ring is to be mounted, and of sufficient length so that when the end of said fitting is completely inserted in said chamber, an O-ring which slips off the edge of said flared end is received directly over the desired mounting position on said fitting; and d. means for engaging a single O-ring and moving it axially over said flared end, thereby mounting said O-ring over a fitting contained within said axial chamber, comprising: 1. a support, 2. a pair of fingers pivotally mounted on said support and spring biased toward the closed position, 3. means defining a pair of converging cam surfaces, and 4. cam follower means provided at an end of each of said fingers, the arrangement being such that in approaching the uppermost position said cam follower means engage said cam surface means and cause said fingers to open, thereby permitting an O-ring to fall past said fingers, and e. means positioned above said pair of fingers adapted to support a plurality of O-rings mounted on said mandrel and to release a single O-ring on actuation.
Claim 3
Dependent Claim
16 words
a pair of fingers pivotally mounted on said support and spring biased toward the closed position,
Claim 4
Dependent Claim
16 words
a pair of fingers pivotally mounted on said support and spring biased toward the closed position,
Claim 5
Dependent Claim
13 words
An apparatus according to claim 1, wherein said mandrel has a circular cross-section.
Claim 6
Dependent Claim
21 words
An apparatus according to claim 1, wherein said mandrel is vertically mounted and supported at its upper end to said frame.
Claim 7
Dependent Claim
9 words
means defining a pair of converging cam surfaces, and
Claim 8
Dependent Claim
9 words
means defining a pair of converging cam surfaces, and
Claim 9
Dependent Claim
74 words
cam follower means provided at an end of each of said fingers, the arrangement being such that in approaching the uppermost position said cam follower means engage said cam surface means and cause said fingers to open, thereby permitting an O-ring to fall past said fingers, and e. means positioned above said pair of fingers adapted to support a plurality of O-rings mounted on said mandrel and to release a single O-ring on actuation.
Claim 10
Dependent Claim
74 words
cam follower means provided at an end of each of said fingers, the arrangement being such that in approaching the uppermost position said cam follower means engage said cam surface means and cause said fingers to open, thereby permitting an O-ring to fall past said fingers, and e. means positioned above said pair of fingers adapted to support a plurality of O-rings mounted on said mandrel and to release a single O-ring on actuation.
Claim 11
Dependent Claim
82 words
An apparatus according to claim 1, having a pair of substantially parallel travel rods vertically mounted on said frame, the support for said fingers being slidably journaled over said rods through apertures provided therein, and means for raising and lowering said assembly comprising a pivotally mounted operating lever, and a pair of connecting rods each pivotally mounted at one end on said operating lever and at the other end to said support, and means spring biasing said support toward its uppermost position.
Claim 12
Dependent Claim
19 words
An apparatus according to claim 4, wherein said operating lever is provided with a foot pedal for non-powered operation.
Claim 13
Dependent Claim
45 words
An apparatus according to claim 4, wherein said operating lever is actuated by means of an operating disc mounted on a shaft having an off-center operating pin adapted to engage and to move said operating lever, said disc being operatively connected to a power means.
Claim 14
Dependent Claim
99 words
An apparatus according to claim 1, having a pair of electrically actuatable clamp means supporting said mandrel, means operatively connected with said clamp means so arranged that said upper and lower clamps are alternatively opened to permit O-rings to slide to the lower end of said mandrel while still supporting said mandrel, delay means for delaying the opening of said lower clamp until a short period after said upper clamp has closed, and delay means for detaining said lower clamp in open position for a sufficient period to permit the supply of O-rings to drop past said open clamp.
